Flashing works with rpi-Pico-2 but not on rpi-Pico even for 12.8 release I have no NSH overy USB on none :-(
Maybe a built-in bootloader on the SBC needs an update? Note I have RP2-B2 instead bare RP2040 on rPi-Pico. rPi-Pico: UF2 Bootloader v3.0, Model Raspberry Pi RP2, Board-ID RPI-RP2. rPi-Pico-2: UF2 Bootloader v1.0, Model Raspberry Pi RP2350, Board-ID RP2350. Tomek ps/2: dd trick seems to work to flash, but i have no way to verify ;-) On Mon, Apr 14, 2025 at 4:53 PM Tomek CEDRO <to...@cedro.info> wrote: > > On Mon, Apr 14, 2025 at 4:36 PM Bernd Walter <ti...@cicely7.cicely.de> wrote: > > On Mon, Apr 14, 2025 at 04:11:40PM +0200, Tomek CEDRO wrote: > > > Yeah I also had problems flashing this rpiPico boards with USB MSC > > > method (mount+cp+umount) on FreeBSD.. is there a OpenOCD like method > > > so I could try too? :-) > > > > On FreeBSD I never mount and just dd directly to the device with bs=1M. > > That should work for other OS as well. > > I never tried to flash via swd, since the USB method worked fine for me. > > Whoah another FreeBSD user, greetings, and thanks for the hint, will > try and report back :-) > > > > About the pico probe. > > It is a SWD debugger using the DBGU protocoll on USB. > > Already used a pico with pico probe firmware to flash Atmel controllers in > > the field, since the picos are super cheap to get. > > In my lab I use an Atmel-ICE on various Atmel and STM32, which in theorie > > should work as well for the RP2040, but I never used a debugger on an RP2040 > > yet. > > The Atmel-ICE uses DBGU as well, however any OpenOCD compatble SWD adapter > > should work. > > Hmm, I can see using another MCU as the DebugProbe is quite popular, > will try that in a free moment, but I was thinking more about > single-USB-connection stuff as I have many many boards attached to a > single BSD machine over 2x 16-port USB hubs and so every port counts > as separate board :-) > > -- > CeDeROM, SQ7MHZ, http://www.tomek.cedro.info -- CeDeROM, SQ7MHZ, http://www.tomek.cedro.info
